The procedure if you decide you don't want the car is to go to your dashboard and cancel the order. You'll be directed to call the EV center number and they will re-enable your account to that it can be cancelled.
You are under no obligation to purchase the car, you signed no contract to purchase the car, and your dealer should not be applying any pressure to you to purchase the car. You don't even have to give a reason - just decide that you don't want it.
After that it is up to the dealer to sell the car.
Even if you found someone here who wanted the car, the dealer is under no obligation to sell to "your buyer".
If you intended to purchase and then resell - you'll likely have to come up with cash to pay the full price of the car, and the private purchaser tends to need cash too to make the thing go smoothly. It's tough to sell your car before you actually get all of the paperwork back from the state if it is a private sale.
If you think you're going to collect a "finder's fee" from the dealer or a purchaser for finding someone to buy the car - that's someone silly as there is a waiting line for the car so finding real purchasers isn't very hard.
